On an Oasis washer the LD message indicates a problem with the drain pump or an obstruction under the basket.
LD means "long drain" and can be displayed if the drain pump in not working or if something is under the wash basket.
The drain pump must work. If the water is not draining out then the pump can be blocked or just bad.
If the water is draining out of the washer okay but you still get an LD error then there can be something under the basket. This particular basket floats when water enter the tub and when it drains out the basket should drop onto the drive hub. If the basket never drops onto the hub then the control assumes the water didn't drain out.
A sock under the basket can cause this problem as well as a none working pump.
If the washer is not draining then the pump is most likely the cause of this problem.
If the washer does drain okay then there is most likely something (sock?) under the basket preventing it from engaging with the drive hub.
The image below shows how to remove the basket and check under it for any obstructions. Remember to unplug the washer first.
